Measurements and analysis of atomic emission from atomic Li, Na, and K seeded in different flames for potential application to temperature sensing
Alkali metal atoms, especially sodium and potassium, show an intense fluorescence in hot flue gases. The bright fluorescence emitted by alkali metal atoms offers a large potential for spectroscopic combustion analysis. In this thesis, the temperature dependence of the two-component fluorescence intensity ratio Na/K, as well as the three-component ratio Na·Li/K2 was investigated in the flames with
